How does this bode for Foster? We're all used to sketchy reports from the team, but they've been less forthcoming with Foster, who is immeasurably more vital to the team than Wade Smith.

The Texans are insistent that Foster's calf is completely well and no problem. And his back has just for some reason "tightened up on him." It would be remiss to discount that the likely reason for a tight back would be as a back strain compensatory to his calf injury.......something that would be changed by his postural dynamics (core instability) either secondary to adjusting to some residual soreness of his calf, and/or fear of re-injury. Remember, calf strain/tear is associated with a high incidence of later strain of the same calf (re-injury to the same calf can lead to long-term chronic calf problems) or contralateral calf, a combined risk reported as high as 50% .
